The Pence-Kaine debate was supposed to be the exceedingly civil, policy-driven debate, but early on, the two vice presidential nominees found themselves talking over one other as they sparred over Donald Trump's taxes.

Mike Pence, the GOP vice presidential nominee, was asked about a recent New York Times report that showed Trump may have avoided paying taxes for nearly 20 years. After not really addressing the issue the first time it was asked, the Indiana governor said the episode illustrated that Trump "faced some pretty tough times" two decades earlier.

As for not paying taxes, Pence argued Trump used the tax code "just the way it's supposed to be used."

Not surprisingly, this sparked a lively exchange between Pence and Tim Kaine, Hillary Clinton's running mate, as the two proceeded to talk over one other, a pattern that began from the debate's earliest moments.

"He's broken his first promise," Kaine said of Trump's refusal to release the returns.
